ABSTRACT
The variations of thermal conductivity with temperature for Bi [x] at.% Zn 2 at.% Al alloys (x = 4.5, 18.0, 30.1, 79.0 and 98) were measured by using a radial heat flow apparatus. From the graphs of thermal conductivity versus temperature, the thermal conductivity of solid phases at their melting temperature for Bi [x] at.% Zn 2 at.% Al alloys (x = 4.5, 18.0, 30.1, 79.0 and 98) were obtained. Dependency of the thermal conductivity on composition of Zn in the Al Bi Zn alloys was also investigated. According to present experimental results, the thermal conductivity of the Bi [x] at.% Zn 2 at.% Al alloys linearly decrease with increasing the temperature and exponentially increase with increasing the composition of Zn.
